In a genius collaboration, acclaimed authors Kate DiCamillo and Alison McGhee - energized by the art of Tony Fucile - introduce two outrageously funny little girls!Meet Bink and Gollie: two precocious little girls - one tiny, one tall, and both irrepressibly funny.

Setting out from their super-deluxe tree house and powered by plenty of peanut butter (for Bink) and pancakes (for Gollie), they share three comical adventures involving painfully bright socks, an impromptu trek to the Andes, and a most unlikely marvellous companion.

No matter where their roller-skates take them, at the end of the day they will always be the very best of friends!
